MORGAN ADVANCED MATERIALS: Alumina-Based Ceramic Cavities for Laser Reflectors
The Technical Ceramics business of Morgan Advanced Materials has expanded its capabilities in producing standard and customized high-reflectance ceramic cavities in laser reflectors. High-performance alumina-based ceramic reflectors for solid-state lasers are reportedly ideal for a wide variety of industrial and healthcare applications, including cutting and welding, marking, or even hair and tattoo removal. According to Morgan, its Sintox AL material, a porous high-purity alumina (99.7% Al2O3), provides high strength, good thermal conductivity, and excellent dimensional and electrical stability in the operating temperature range.
Longer lasting and featuring high reflectance over a wide wavelength range, Sintox AL reportedly provides a cost-effective alternative to metal-coated reflectors. It exhibits high reflectance (97-99%) over an optimum reflectance range from 570-2000 nanometers (nm). Process control and repeatability allow production of material with controlled porosity, which is a necessity for high-quality laser light generation.
Morgan offers three proprietary glaze options that protect the underlying porous ceramic from cooling fluids in operation and can be colored to restrict wavelength range. A clear yellow glaze absorbs radiation at the Nd-YAG lasing wavelength of 1064 nanometers (nm), and further transitions near 940, 1120, 1320 and 1440 nm. A high-absorption samarium oxide glaze is formulated through the controlled addition of dopant to create optimum reflectance properties. The samarium oxide glaze matches yellow and clear glazes between 700-900 nm for reflectance.
With the design capability to produce customer-specific solutions and standard products, Morgan offers one- and two-piece options, as well as complex geometries. Components up to 250 mm long and with diameters up to 80 mm are standard.
